How secure is your Full Disk Encryption? #openSUSE digs deep into mitigating rogue device attacks using #TPM2, #PCR extensions, and custom #initrd validation. A must-read #FDE for #sysadmins & #security pros. #opensource https://news.opensuse.org/2025/07/18/fde-rogue-devices/

Gibt es hier #Sysadmins die #Jira betreiben?
Und zwar im selfhosted Datacenter mit 2 oder mehr Nodes?

Ich bräuchte bitte eine Verifikation.
Ab mindestens Version 9.12.34, wahrscheinlich schon ab 8.5.x

Könntest du bitte folgendes tun?
Jira auf einem Node stoppen
Im Local Home
/var/atlassian/jira/plugins
- die beiden Dotverzeichnisse löschen (.osgi-plugins und .bundled-plugins)
- sämtliche jar-files aus installed-plugins irgendeo hin verschieben, damit es leer ist
- jira restarten

Wenn Jira wieder da ist, müssten die beiden Dotverzeichnisse wieder angelegt sein und installed-plugins müsste wieder mit jar-Files gefüllt sein

Die Dot-Verzeichnisse kommen wieder, aber bei mir bleibt installed-plugins leer. Auf sämtlichen Umgebungen. Und ich will herausfinden ob es ein Bug in Jira ist, oder in unserem Setup.
Daher bräuchte ich eine unabhängige Verifikation.

Must read für alle #Sysadmins: Heute hat das #BSI seine neue #Cybersecurity Empfehlung für #Mail-Sicherheit publiziert.

Erklärt wird anhand von konkreten Praxisbeispielen und Konfigurationsmöglichkeiten, wie die Cyber-Sicherheit der E-Mail-Kommunikation mit Kundinnen und Kunden sowie anderen Unternehmen oder Dritten verbessert werden kann. Außerdem wird auf häufige Fehler hingewiesen, die die #Cybersicherheit schwächen:

Happy #WorldPenguinDay!
Did you know #Tux, the #Linux mascot penguin, was designed by Larry Ewing in 1996 using the #opensource graphics tool #GIMP? The name “Tux” was chosen as an acronym for ‘Torvalds’ UniX’ and a reference to the black-and-white “tuxedo” appearance of penguins.

Quick question for #sysadmins and #netadmins : do the AI scrapers use IPv6 addresses ?

I wanted to try something at home, but since you have more logs than me, it might be interesting to share this :)

A question for all the #selfhosting enthusiasts and #sysadmins out there:

I had a Go site on a VPS and recently decided to migrate to self-hosting Ghost on a Digital Ocean VPS (I was using Oracle before) and my site has become basically inaccessible. I checked the RAM usage in my admin and it's consistently above 90%. I have 1GB ram and figured I wouldn't need more since I don't get much traffic, but now everytime I try to open my site it takes forever to load.

What I don't understand is that, on the Oracle VPS, I not only had my Go site, but also had Caddy, Plausible for analytics with a #postgres DB and never had any issues. Now, all I have is the ghost site, mariadb, and caddy and nothing works.

Do I need more RAM or is this a DO thing? Both the Oracle and DO VPSes are hosted in the EU which is pretty far from here, to be fair. I do suspect it's a RAM issue because I can't even ssh into the VPS. When I try to open my site, the connection just loads until it eventually times out.

Ubuntu 24.04 system with a publicly-routable external IP address.

For a given incoming UDP port (<1024, call it port x, I can’t change this), I want to forward that to localhost (or the ens3 interface) on another port (>1024, port y) so I can invoke QEMU as non-root and forward port y to the emulated system’s port x via slirp.

Is this doable?

I’ve tried heaps of nat prerouted examples, but haven’t yet gotten anything to stick.

Boosts appreciated!

@falcennial it's helpful for #sysadmins and anyone who is running their own #firewall (regardpess if WAF, hosted/managed or DIY/bare metal), as they can just pull that Feed-URL to (un)block stuff automatically...

• I wished #Mastodon #developers would realize that supporting a Blocklist Feed is kinda crucial function as noome wants to spin up *yet another git just to diff&merge stuff because they only offer "add" and "replace" when it.comes to #CSV / #TSV input.

To all #sysadmins

What #Linux distro's you use in your job currently?

@GossiTheDog

The update results in #Exchange #crashing and being unable to deliver #mail reliably.

#Microsoft is currently working on a method for #sysadmins to determine if the update is affecting their servers in this way, or if it's just normal Exchange operation.

Fellow #sysadmins, #Emacs, and #FOSS people: If you use emacs -nw or emacs-nox11 in a remote SSH session, how do you deal with keybinding interference with terminal multiplexers? The only reason I use (Neo)vim in remote SSH sessions is because Emacs keybindings would interfere with my local Zellij instance and sometimes the remote Byobu/tmux session.

One possible solution is to change the Zellij keybindings. Another possible solution is just to connect to the remote systems via Emacs' tramp session and edit files that way, but IME that has been buggy and doesn't have a native feel. Plus if I have to use sudo to edit a file, it has to start a whole new tramp session. Another possible solution that may or may not be doable is starting an Emacs server on the remote host and connecting to it locally, but I'm not sure if this is possible yet.

I've tried more lightweight members of the Emacs family, like mg or zile, but those still have most of the same keybindings as regular Emacs and they are lacking in terms of configurability. I'd also like to have at least some basic syntax highlighting, nothing fancy.

Of course, VSCode has these features builtin with their Remote SSH Explorer, and even has a nice UI that allows one to select different SSH hosts. I feel like Emacs can be made to do exactly this, but tramp mode just feels... idk... clunky.

To all my fellow #sysadmins , be you #networkengineer , #dba , #sysdmin , or #finops , a very happy #sysadminday !

You keep everything working. Thank you.

Moin zusammen,

haben wir hier ein paar Raid Experten für Linux SW Raids ?

Ich renne langsam in mein know how limit, an einer meiner Maschinen hat sich von den Hetzner nvme´s einfach der SW Raid aufgelöst.

Und ich frage A warum B wie und C kann ich die Paritionen einzeln wieder zusammenknüpfen ohne Datenverlust ? Und wenn ja wie ?

System ist nen Debian 12
